The grid tile connector 600 includes elevated wall segments 602, a flat bottom 604, locating wells 606, corner posts 608, and reinforcing ribs 614. The corner posts 608 include counter bored holes 610 with threaded inserts 612 (see FIG. 37). The outer perimeter walls are elevated to reach the bottom 264 of the grid tile 260 for additional support. The legs 300 pass through the locating wells 606 and rest on the surface of which the wire harness grid tile 260 is set. The fit between the inner surfaces of the locating wells 606 and the outer surfaces of the legs 300 is relatively close thereby resulting in an improved rigidity for the wire harness tile assembly. The counter bored holes 610 with the threaded inserts 612 are aligned with the holes 268 in the harness board grid tile 260.

As illustrated in FIG. 38, an alternative embodiment of a joiner plate or grid tile connector 620 includes a flat bottom 622, corner posts 626 and reinforcing ribs 634. The flat bottom 622 has holes that accommodate the legs 300 of the wire harness grid tiles 260. The corner posts 626 have counter bored holes 630 with threaded inserts. The threaded inserts are pressed into the counter bore holes 630 from the underside so that they cannot be pulled out by fasteners 170 if they are overtightened.

FIGS. 39-41 illustrate joiner plate or grid tile connector 700. The grid tile connector 700 includes a flat bottom 704, locating wells 706, corner posts 708, and reinforcing ribs 714. The corner posts 708 include counter bored holes 710 with threaded inserts 712 (see FIG. 41). The legs 300 pass through the locating wells 706 and rest on the surface of which the wire harness grid tile 260 is set. The fit between the inner surfaces of the locating wells 706 and the outer surfaces of the legs 300 is relatively close thereby resulting in an improved rigidity for the wire harness tile assembly. The counter bored holes 710 with the threaded inserts 712 are aligned with the holes 268 in the harness board grid tile 260.

Fasteners 170 are used to secure wire harness grid tiles 60, 260 to the grid tile connectors 600, 620, and 700. As many wire harness grid tiles 60, 260 may be used to form large wire harness assemblies of any size having dimensions equal to multiples of the individual wire harness grid tiles 60, 260. The grid tile connectors 600, 620, and 700 are used to fasten adjacent wire harness grid tiles together to ensure accurate alignment of the wire harness assembly system.

The wire harness assembly system described and illustrated herein is flexible and inexpensive. The wire harness grid tiles and the key locking mounts are easily assembled to form the wire harness assembly system required by the end user. The keyed locking mounts and various mounting fixtures are interchangeable and easily adjusted by the user, as desired. The keyed locking mounts and various mounting fixtures are made of a plastic material with the exception of the nails which may be made of steel or a plastic material.
